@Application led April 9, 1913. Serial No. 759,834.

To alimen/limitait muy concernl Be it known that we, ARCHIET. MGAL-Lrsrnn and HARRY DrPPEL, citizens of the' -United tates,A residing. inythe city and county of .Philadelphia Jand State of Penn- Sylvania, haveinvented certain new and use- Yful Improvements in Hangers for ConcreteWork, of which the following is a specification.

`Our invent-ion relates td hangers adapted to be embedded or molded inconcrete workf be anchored(` on the usual metal rods .em-

ployed to reinforce the concrete and which will be provided with spacedor open parts between which the concrete may extend so' that the hangerwill be roperly anchored, all as will be hereinafter ully described andparticularly claimed.

Inv the accompanying drawings, illustrating our invention: Figure 1, isa plan of our improved hanger. Fig. 2, is a' vertical section thereof,on line 2-2 of Fig. 1. Fig. 3,

is a side view of the partls'of they hanger, slightly separated fromeach other. Fig. 4, is a vertical section through a portion of a moldfilled with concrete, showing the hanger secured to the floor of themold and embedded in the concrete therein.

Referring to the drawings, our hanger, in the preferred form ofembodiment of our invention is -made\in three parts, a central bodyportion 3, a member or spider 4 above and laterally of the body portion3 and a head 5 above the member 4. l. p

The body portion 3 is made in the form of a verticallyarranged blockhaving upper and lower end aces 6 and 7 respectively, in parallel,horizontal planes and having an interiorly screw-threaded opening 8extending vertically 'hito the lower end thereof and adapted to receivethc screw-threadedl like upper portion 9, having a hole 10 in the centerthereof, and inclined arms 11 extending outwardly and downwardly fromthe portion 9 in spaced relation to each other and in spaced'relatio'ito the central hbody portion 3. The lower ends of the arms are providedwith outwardly extending flanges l2 having holes 13 therein for thereception of nails or other devices to secure the arms tothe concretemold, as will be hereinafter explained.

The head 5 comprises a lower, horizontalY portion 14, arms 15 extendingupwardly and outwardly from the sides of th horizontal portion 14, ahorizontally-arranged ring 16 vconnecting the upper ends of the arms 15and a central, screw-threaded shank 17' 'extending downwardly from theportion 14.'

In assembling the three parts 4 and 5, i

the upper port-ion 9 of the vmember 4 is placed upon the upper `face 6of the body portion 3 and the shan-lr 17 on the head 5 is passed throughthe opening 10 and screwed into an interiorly threaded hole in the upperend ot the body portion 3, thus clamping the member 4 firmly between thcbody portion 3 and the head 5. When. the parts are thusassembled.y thebottom faces 18 of the arms 11 are in the same horizontal plane with thebottom face 7 of the block 3, and the axis of the opening S extends atright angles to this plane.

Our improved hanger is usually employed in the concrete forming theceiling of a room, and, ,inl this connection, prior to. the formation ofthe ceiling, the hanger is placed upon the wooden board A19, as shown inFig. 4, with the bottom faces 7 and 18` ot' the body portion 3 and arms11 against the top of the board 19 or floor -of the mold. 'lhe lowerends of the arms 1 1 are then secured to the board 19 by driving nails2O through the openingsl 13 and into the board 19, thus holding thehangerv in place with the axis of the opening 8 in true position atposition at right angles to the bottom face of theconcrete or ceiling ofthe room.

When metal reinforcing rods are used in the concrete, the same may beplaced to extend beneath parts of the arms 15 and ring 1G, as shown at.22.511 Fig. 4t, and these rods 22 serve to more tlrmly anchor the hangerin the concrete.

By ,the construction of our hanger, the same may not only be firmlyanchored in the concrete, but the parts serve to maintain the bodyportion 3 in trne position guarded by the arms l1 so that the raking andspreading of the concrete, the walking of workmen over the hanger andthe rolling of wheelbarrows over the wet concrete and the hanger willnot disturb theft-rue position of. the body portion 3.

`We claim: f 1. A. hanger for concrete work comprising a central bodyportion, a member engaged with the upper portion ot the body portion andhaving spaced arms extending downwardly therefrom, and means forsecuring said member to the body portion, said arms having` bottom facesin the same plane with a bottom tace of the body-'porJ tion, said facesbeing adapted to restnpon the door ci' a concrete mold, and the lowerends of said arms being adapt-ed to be secured to said door.

2. A hanger for concrete work comprising a central body portio'n, amember engaged with the top of the bo'dy portion and having spaced armsextending downwardly therefrom, anda head engaged with the top o't saidmember and having a screw-threaded shank extending through said memberand screwed into said body portion, said arms having bottom faces in thesame plane with a bottom face of the body portion, said facesbeingadapted to rest upon the oor of a l concrete mold, and the lowerends of said l arms being adapted to be secured to said floor.

3. A hanger for concrete work comprising a lcentral body portion, amember engaged with the top of the body portion and having spaced armsextending downwardly there from, and a hcad engaged with the top otsaidvmember andv having a screw-threaded shank extending through saidmember and screwed into said body portion, said head being provided withupwardly and out 'ardly extending arms, the arms oit' said member havingbottom faces in the same plane with av bottom face of the body portion,said faces being,` adapted ,to rest upon the. Hoor of a concrete mold,and the lower ends of said arms being adapted to be secured to saiddoor.

Ll. A hanger for concrete work comprising a central body portion, amember engaged with the top of the body portion and having spaced armsextending downwardly there from, and a head engaged lwith the top oisaid member and having a screw-threaded shank extending, through saidmember and screwed into said body portion, said head being provided withupwardly extending 'arms connected at their upper ends by ahorizontally, arranged ring, the arms of said member having bottom facesin the same plane. with a bottom face ot the body portion, said facesbeing adapted to rest upon the iioor of a concrete mold, and the lowerends of said arms being adapted to be secured to said floor. Intestimony whereof we alibi our signatures in the presence of twoWitnesses.
